And Control

Inventory control strategy of spare parts is an effective way to improve equipment support efficiency and scientific and reasonable inventory policy can make spare parts availability reach the upper limit. Multi-echelon integrated inventory control strategy of equipment spare parts is studied. Three-level integrated inventory control model consisting of rear warehouse, equipment using units and spare parts supplier is established according to the architecture and control program of multi-echelon joint inventory. The algorithm of solving the proposed model is analyzed and a numerical example is provided. The proposed equipment spare parts inventory model can improve inventory quality to a certain degree and decrease the contradictions between inventory and maintenance. The correctness and effectiveness of the proposed model are verified by the example, which provides an effective model for equipment spare parts inventory.

Replenishment Cycle

Control model for spare parts inventory is established based on the optimal replenishment cycle. The replenishment cycle impact on the spare parts inventory control is analyzed as well as the demand forecasting. First, the optimal replenishment cycle is given by using the method of the lowest cost of inventory. Then according to the demand characteristic of the spare parts, the safety stock can be calculated. Finally on the basis of the demand forecasting, the calculation method of spare parts replenishment quantity is given. A numerical example is presented to verify the validity and practicability of the model.
